Woodward speed switches defend your engine or equipment against the damaging and dangerous conditions of overspeed and underspeed. Our speed switches offer many choices—from single-channel, manually adjustable models to multiple-channel, software configurable models.

Woodwards UMT 1 Series consists of measuring transducers that feature true RMS sensing. Measured values are calculated and displayed on a two-line, 16-character LC Display. They can either be assigned to analog outputs (configurable as -20 to 20 mA, 0 to 20 mA, or 4 to 20 mA) or transmitted to a higher-level control system via RS-485 or Profibus DP interface. The primary measured values of voltage and current are used to calculate the values for active, re-active, apparent power, power factor (cosphi), kWh and kvarh. An impulse output is also provided to output kWh or kVarh values.

Feature : True RMS sensing , Class 0.5 accuracy , RS-485 Modbus RTU Slave or Profibus DP communication

Woodward’s SPM-D synchronizer is used on steam turbines with three-phase AC generators utilizing compatible speed controls and automatic voltage regulators. The SPM–D provides automatic frequency, phase and voltage matching, using either analog or discrete output bias signals (depending on model). The SPM-D digitally measures true rms values, ensuring measurement accuracy and maintaining integrity against harmonics, transients, or power spikes. A quick-mains decoupling function permits the SPM-D21 to operate in mains- parallel applications without additional external protection relays.

Features : simplifies the design of the switchgear cabinet,facilitates the commissioning

Gas-fuel metering valves are essential for low emissions, and Woodward offers fuel metering technologies suitable for a range of engines, from alternative-fuel bus and truck engines to large industrial gas and dual-fuel engines. TecJetTM valves provide precise, full-authority control fuel mass flow using on-board electronics and pressure and temperature transducers, and are often used with biogases or other fuels having varying heat content

The patented dirt tolerant and self-cleaning technology of Woodward's VariStroke actuators ensure greater overall reliability of your steam turbine. The VariStroke line of linear electro-hydraulic valve actuators operate mechanical-drive or generator-drive steam turbines. These linear actuators utilize a low-pressure, hydraulic oil source (typically turbine lube oil) to provide output shaft force. Their superb accuracy and resolution make them ideal for steam valve control and related turbine speed and load control, where turbine up-time and availability is essential. The VariStroke line is configurable via a simple user-friendly, computer-based PC service tool, allowing users to easily configure, calibrate, and adjust all internal functions and response settings. Its integrated driver includes a 4-20 mA output channel to indicate output shaft (control valve) position, as well as unit alarm and shutdown relay outputs for use as unit health and status indications. The 4-20 mA demand inputs and dual-redundant shaft position sensors allow it to continue to operate even with demand input or feedback sensor failures, ensuring extended run-times between forced outages and on-line system repair. The total installed cost for this fully-integrated actuator is low because it is completely assembled and tested at the factory, greatly reducing OEM and end-user fabrication, testing, and site assembly time. In retrofit applications, the VariStroke actuator can be used to directly replace the existing servo system. This saves costly repairs to existing and aging servos, eliminates the difficulty of obtaining spare parts for obsolete equipment, and reduces calibration time and difficulty.

Woodwards Swift valve is a highly accurate, low- cost system, which controls fuel to the turbine or high-pressure fuel cell. It is designed for high pressure applications (50—250 psia), and the unique design yields a linear flow characteristic unaffected by discharge pressure up to a pressure ratio (P2P1) of at least 0.85. The design integrates the valve and actuator into a compact, efficient assembly.

Woodwards SonicFlo hydraulically actuated valve controls gas flow to any size industrial or utility gas turbine. The unique design yields a linear flow versus stroke characteristic that is unaffected by discharge pressure up to a pressure ratio (P2P1) of at least 0.8 for Standard Recovery and at least 0.92 for High Recovery. (Optional flow profiles are available.) The integral hydraulic actuator is a single-acting, spring-loaded design for failsafe operation. The servovalve is electrically redundant with a triple coil design and dual or triple redundant LVDT’s (linear valve displacement transducers). Valve sizes are available from 2” to 8,” with multiple flow profiles for each valve size. ANSI Class IV seat leakage is standard, with an optional Class V available. Optional Trip Circuits are available to fit any application.

The switches are adaptive to most speed-related switching functions on diesel and gas engines and other rotating machinery. In addition to generator sets, starter motors, and engines, ESSE switches are also used on diverse equipment such as conveyor belts, bus doors, and magnetic brake retarders. Both single and dual setpoint models are potted for protection against harsh environments and have proven to be reliable and rugged as well as flexible and cost effective.

RTCnet is a rugged distributed IO solution for use with Woodward turbine controls. It is the first distributed IO that not only supports Woodwards deterministic rate- group, real-time operation, but that is also fully synchronized with the main control processor. RTCnet offers Woodward customers all the benefits of MicroNet real-time performance in a distributed, compact solution. RTCnet features redundant CAN communication ports for high availability in demanding turbomachinery applications. It can be used for high performance control loops where general purpose, asynchronous distributed IO cannot. RTCnet has an ultra -rugged, all metallic DIN-rail mount packaging suitable for skid mount and turbine enclosure installations. The lightweight packaging can sustain high vibration, 40 G shock, and a wide (�40 °C to +100 °C) temperature range. It is marine compliant (e.g., rated for high-humidity areas). It also has 500 V (ac) isolation to protect against damage due to wiring errors and to ensure reliable operation in the harshest EMC environments.

Woodwards ProTech-SX SIL 2 PLC safety system applies to steam, gas, or hydro turbines, plus plant process equipment. This stand-alone safety system accepts two speed inputs and seven discreteanalog inputs, uses programmed logic to determine when a safety event has occurred, then issues system shutdown commands and alarms. The ProTech-SX uses five fast-acting, configurable relay outputs and a speed meter output to interface withcommand the specific system or device being protected.

Woodwards ProTech®-GII is an overspeed safety device designed to safely shut down steam, gas, and hydro turbines upon sensing an overspeed or over acceleration event. This device accurately monitors turbine rotor speed and acceleration via active or passive MPUs (magnetic pickups) and issues a shutdown command to the turbine’s trip valve(s) or corresponding trip system.

The ProAct Integrated Throttle Bodies (ProAct ITBs) are butterfly valves electrically actuated by ProAct actuator s to control flow output. With bore sizes ranging from 85 mm to 180 mm, these ProAct ITBs are designed for use with engines in the 1 MW to 2 MW range. This is an electromagnetic actuator with 75 degrees of travel, which alleviates the problems associated with linkages on gas engines (such as setup, non-linearity, and wear). This direct combination of throttle and ac tuator results in excellent stability and transient characteristics, and requires no hydraulics, pneumatics, or governor gear train. Therefore, you end up with an efficient, long lasting, and easily-installed throttle option.

The SOGAV valves are a family of electrically-actuated, high-response gas admission valves for in-manifold (port) fuel admission. The SOGAV valves are designed for use on four-cycle, turbocharged, natural gas or dual-fuel engines. One SOGAV valve is required for each cylinder. The SOGAV valve is designed to be used as the valve portion of an overall gaseous fuel admission system delivering precise gas mass flow metering per cylinder. This enables gas engines and dual-fuel engines to operate lean burn, increased efficiency, and reduced emissions. Ask Woodward for information on the newest SOGAV models, which allow a wider range of pressures and improved field service.

Woodward’s MicroNet programmable control is applied on any prime mover and its processes including sequencing, surge, vibration, stationhigh speed system control and monitoring. The MicroNet digital control is available in both simplex and triple modular redundant (TMR) configurations.

Magnetic pickups (MPUs) are speed sensors that detect the speed of a prime mover, typically an engine or turbine. They are the communication link between your engine and a Woodward electronic governor control. The MPU is installed next to a drive shaft gear made of a material that reacts to a magnetic field. As each gear tooth passes the MPU, the gear interrupts the MPU's magnetic field, and an alternating voltage is developed. The frequency of this voltage is translated by the speed control into a signal that accurately depicts the speed of the prime mover. Woodward’s magnetic pickups can be used with most electronic speed controls. Models are available for hazardous location installation.

The LQ6 provides the flow range, accuracy, and response characteristics necessary for the control of industrial gas turbines in the 3 to 15 MW power range. By integrating Woodward’s proprietary electric actuation technology with a proven fuel-metering concept, exceptional performance and robustness are achieved in a compact, cost effective package. The use of on- board driver electronics simplifies system design and reduces installation space, time, and cost. Please refer to Woodward Installation and Operation Manual 26515 for complete details of this product, its application and installation.

The Liquid Shutoff Valve is a three-way valve designed to rapidly shut off all liquid fuel flow and prevent leakage to the turbine. In the de-energized state, the valve diverts inlet flow to bypass ports, preventing pressure damage to positive displacement fluid systems. Normal installation of the 21.5 pound (9.8 kg) valve is in the fuel line between the fuel regulating valve and the turbine. The valve diverts flow from the discharge to bypass ports anytime the operating electrical signal is lost. The valve is available in four voltage configurations.

DYNA 2000 and DYNA 2500 linear actuators provide precise positioning with a minimal number of moving parts. Many of the moving parts normally associated with electric actuators are eliminated, prolonging the mean time between failure. These DYNA actuators are suitable for installation on diesel, gasoline, or natural gas engines with fuel system force requirements of less than 13 pounds (58 N) of force. When paired with a Woodward controller, precise isochronous speed control of 5 to 30 HP engines (DYNA 2000) and 5 to 60 HP engines (DYNA 2500) is achieved. Both actuators are easy to install by mounting near the fuel system and direct connecting to the fuel control rod or lever. In most installations, the normal rotary-to-rotary connection is eliminated, resulting in a more trouble-free and accurate control system.

The L-Series Position Controller accepts a position command and drives the 0–60 degree output shaft to the commanded position based on an internal shaft position sensor. The high-efficiency torque motor delivers 0.34 N*m (0.25 lb-ft) nominally over 60° travel range to operate fuel or air control devices (see specifications for torque performance over the full product temperature range). The L-Series Position Controller accepts either a PWM, 0–5 V, or CAN command for output positioning. The command signals are issued by the appropriate supervisory engine management system, and the L-Series must be set up properly in software to expect the correct signal for the application. For status purposes, a relay driver output is available on the L-Series control which changes state whenever a fault or error condition is experienced by the controller. The L-Series provides a direct position output signal in the form of a dc voltage if required by the system. The throttle position (TPS) output represents full counterclockwise-to-clockwise rotation of the actuator shaft, and thus gives the operator an external position indication. Besides the traditional bracket mount using external linkage, the L-Series control is available in a variety of mechanical configurations, including integration with diesel fuel pumps, throttle bodies, and mixers (product spec 03222). The shaft rotation can be configured for clockwise or counterclockwise rotation for increasing fuel. For information on Woodward throttle body applications, refer to manual 26249 (ITB and LC-50).

The L&S-400 Distributing Valve is a high pressure, low volume valve for hydroelectric turbine governors Higher performance than mass produced two stage valves Cost effective spare parts Digital driverdiagnostics system with digital communications Design allows for the mounting of valve assembly near or at servos for best valvehydraulic stability, and for most cost effective piping arrangements

The Woodward L-Series Integrated Engine Control System is the first engine speed control to deliver so much in a package this compact. It can also deliver a big savings in production and field support. Since the L-Series Control System is microprocessor-based, it can easily be programmed to match the operating parameters of every engine you produce. The With many built-in functions, this microprocessor-based speed control allows a high-volume OEM or packager to stock one part number, but implement a wide variety of engine control strategies by configuring the four auxiliary inputs at their factory. Besides the traditional bracket mount using external linkage, the L-Series Control System is available in a variety of mechanical configurations, including one integrated into a rotary diesel fuel pump and one integrated with a throttle body or a throttle body and mixer (product spec 03222). The externally mounted systems can be configured for clockwise or counter-clockwise (standard) shaft rotation for increasing fuel. The L-Series control’s high-efficiency torque motor delivers 0.34 Nm (0.25 lb-ft) nominally over 60° travel range to operate fuel or air control devices (see specifications for torque performance offer the full product temperature range).

The programmable Hydro 508 controller drives electric generators for hydro turbines for its hydraulic control system or auxiliary functions. Its configurable program caters for both Francis and Kaplan turbines.

The PG-EG Actuator converts a given electrical input signal into a proportional hydraulic output shaft position, to control engine fuel flow. The actuator provides the muscle for Woodward analog and digital controls. The PG-EG Actuator is available with several servo options, giving a full range of work and torque output (see table on next page). All current PG governor bases (designed to exactly fit any drive designed for a PGE locomotive governor, PGA or PGG governor) can be used with the PG-EG. The proven PG pump and accumulator is reversible or may be set for one-way rotation (advised for generator applications). The actuator uses standard PG output s hafts and power levers. The PG-EG actuator will adapt to most engines being built today and is available for retrofit to most existing engines, in many cases with out changes to linkage drive or other configurations. Maintenance procedures are similar to those needed with a PG governor. The actuator's electric-to-hydraulic trans ducer uses a Woodward-built torque motor which converts the 0–200 mA control signal to a given output position. This actuator is available for use with ei ther direct- or reverse-acting electronic controls. Direct-acting actuators will cause a shutdown if the electrical current to the actuator is lost or interrupted. Direct- and reverse-acting units use the same hardware and can be re-calibrated from one into the other. A 140 μ m wire-mesh filter is accessible from the outside of the PG-EG. The filter protects the small orifice in the pilot valve, which is an integral part of the electric actuator.
